Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed August 30, 1905. Serial No. 276,859.

To all whom it may concern:

Be it known that I, EUGENE F. FILE, a citizen of the United States, residing at New York, borough ofBrooklyn, county of Kings, have invented a new and useful Attachment for Leather-Staking Machines, of which the following is a specification.

My invention consists of a novel construction of an attachment for leather-staking machines whereby the skins are uniformly perched, buffed, and brushed in one operation and a large amount of time and labor saved.

It further consists of novel means for mechanically perching out the skins whereby the grain is opened ready for finishing in a more efiective manner than it can be done by hand.

It further consists in a novel arrangement and a novel manner of assembling the different parts of the attachment and the staking devices.

It further consists in a novel construction of perching, buffing, and brushing elements, each of which is independently adjustable.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents a side elevation of an attachment for a leather-staking machine embodying my invention. Fig. 2 represents, on an enlarged scale, a perspective view of the lower jaw having the buffing, perching, and brushing devices secured thereto. Fig. 3 represents a vertical section on line x at,

Fig. 2. Fig. 4 represents in detached position a perspective view of one of the rolls and its adjuncts. Fig. 5 represents a perspective view of the brush and its bracket employed. Fig. 6 represents a perspective view of the buffer and its adjuncts.- Fig. 7 represents a vertical section on line y g Fig. 6.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a leather-staking machine of any usual or conventional type, although I prefer in practice to employ a machine which is preferably constructed according to Patent No. 604,560, granted to James Craig and Frank F. Slocomb on May 24, 1898, which type of machine I have found to give best results in practice, although it is apparent that the broad principle of my invention is applicable to any leather-staking machine wherein the staking-jaws are reciprocated and opened and closed in the manner familiar to those skilled in the art.

In the type of machine which I have here selected as illustrative of one application of my invention, 2 designates an upper jaw and 3 a lower jaw, said machine having a suitable knee-actuated device 4, adapted to oscillate or regulate the lower jaw 3, as desired. As the construction and operation of leatherstaking machines of this general character are well known to those skilled in the art and are fully described in the patent hereinbefore referred to, I have deemed it unnecessary to enter into a detailed description of the same.

5 designates a roller preferably lined with rubber, gutta-percha, or the like and mounted in bearings 6, supported from the arms 7 of the bracket 8, said parts being suitably retained in assembled position by nuts 9 or the like.

10 designates a slot in the bracket 8, adapt ing the latter to be adjustably fastened to the upper jaw 2 by means of a bolt 11 or the like.

12 and 13 designate rolls rotatably mounted and ad'justably secured to the upper jaw 2, it being seen that in the present instance the intermediate roll 12 is of slightly-larger diameter than the inner roll 5 and outer roll 13.

It will be understood that in practice the rolls 5 and 13 are made capable of vertical and lateral adjustment relative to roll 12, which adjustment is substantially as described in the prior patent hereinbefore referred to, to which-reference may be had for a detailed description of this feature. Roll 12 is not adjustable vertically.

14 designates a brush having fastened to its back the arms 15, having slots 1.6 therein adapting the brush to be adjustably secured to the outer portion of the lower jaw 3, substantially under the roll 13, by means of screws or bolts 17 and nuts 18 or equivalent devices. I

19 designates a plate having slots 20 and 21 therein, said plate being attached to the lower jaw 3 by means of bolts 22 passing through said slots and having nuts 23 therefor.

24 designates lugs extending outwardly from each side of the plate 19 and having openings therethrough adapted to receive the threaded rods 25, which are held in adjustable relation to said lugs by means of nuts 26, located on each side of said lugs.

27 designates a bracket or plate fastened to the rods and having suitably attached thereto, by means of bolts 28, a staking knife or blade 29, which is normally located between the rolls 12 and 13.

30 designates walls or ways on the plate 19, between which a buffer-bracket 31 is adapted to be secured, said bracket having a laterallyeXtending arm 32, which latter is provided with a slot 33, adapting the bracket to be adjustably attached to the arm 19 by means of a bolt 34 or other equivalent fastening device. The bracket is recessed at 35 in order that a buffer-supporting plate 36 may be attached thereto by means of the bar or plate 37 and having the bolts 38 passing through the bracket, buffer-plate, and the bar 36, said bolts being provided with nuts 39. 4O

designates the buffer-block, having the buffing material 41 thereon, said block being suitably fastened to the. buffer-plate 36 by screws 42, it being noted that the buffer is located between the rolls 5 and 12 when the parts are in assembled position. This buffing material is composed of either abrasive or frictional material, such as emery or the like, and this material may be secured to the buffer-block in any suitable manner.

43 designates the skin to be treated, it being apparent from Fig. 1 that the roll 13 is located above the brush 14, the roll 12 being located so as to engage that portion of the skin between the blade 29 and the buffer 40, while the roll 5 engages that portion of the skin which is on the opposite side of the buffer 40, so that during the operation the brushing, perching, and buffing elements will engage the opposite sides of the skin being treated, as desired and according to requirements. All of these elements are independently adjustable, and the staking-blade and buffer may be conjointly or simultaneously adjusted, if so desired.

While I have shown my attachment as being particularly applicable to the machine shown, it is evident that the same may be employed in any leather-staking machine whic is operated in a similar manner.

I have not deemed it necessary to describe the detailed operation of the particular staking-machine shown, as the same is well known to those skilled in the art, it being understood that the jaws advance close and engage the skin at their extreme forward movement, retain their engagement therewith during their backward movement, at the end of which time they open and release the skin, which can then be shifted by the operator according to requirements, after which the jaws advance and engage the skin, as before.

The skin willbe perched, buffed, and brushed in one operation. The perching will open the grain for finishing and perform the operation much more uniformly than it can be done by hand.

My attachment is capable of performing the work of three men, and as the cost of the labor is the most expensive part of this industry the economy which is brought about by the use of my novel attachment is apparent.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
